This is an open access book. The Mongolian National University of Education has successfully organized the "Quality Assurance in higher education" International Conference for 16 consecutive years since 2016. The scope of this conference grows year to year, increasing in quality and participants. Furthermore, in 2018, the conference website was launched (www.qahe.msue.edu.mn) and started partnering with sponsor organizations. A total of 33 papers will be discussed at the plenary and three sessions of this conference named "Education Quality Policy and Implementation," "Innovation of Teaching and Learning Technology and Contemporary Trends," and "Teaching and Learning Technology Implementations and Outcomes." There are five poster presentations. The research volume on high education quality and its relevant disciplines has increased. We hope that the conference will contribute experiences and knowledge about policymaking and research worldwide.
